Showing great restraint

Sitting with a nurse practitioner or a physician's assistant or something like that, yesterday, as she updated my prescription list:

NP/PA: Ok, you're still taking the Tacrolimus and the hydrocortisone ... Fluconisole, hmm. Do you have a spleen?

Because she isn't one of the team who's used to me, I refrained from reaching for my wallet and saying "Do you have change for a kidney?"
